jbooker82 Posted May 25, 2010 Report Share Posted May 25, 2010 iw24 is the 9's...iw27 is the 8 series Are you sure about that. Look up BR8EIX on www.sparkplugs.com then cross referance it to other brands. It shows the Denso IW24. Then do a seach for BR9EIX it shows the Denso IW27 as the cross referance. Here is there Heat Range Cross Referance chart. Quote Link to comment Share on other sites More sharing options...
stroking Posted May 25, 2010 Author Report Share Posted May 25, 2010 GV= Gold-palladium center electrode Special Construction of V-Type. Racing use http://www.ngksparkplugs.com/docs/tech/partnumberkey.pdf so far it seem to be the best plugs ive tried....B9EGV's gives better throttle response than all the others.

RedStrapperRacing Posted May 25, 2010 Report Share Posted May 25, 2010 I have ran the BR8IEX's same heat range as the stock plugs. I have seen the denso iridums they are a better design. They have a finer wire center electrode. I believe they are IW24. Another plug that I run is a BPR8ES same plug as stock only the tip is a projected tip. It hanges down in the combustion chamber. Then you side gap them. I have run the BR9IEX's - The only difference I've noticed is the crazy price difference between them & the BPR9ES Quote Link to comment Share on other sites More sharing options...
